Abstract:

The construction of vehicle urea production unit by urea production enterprises helps to increase the additional value of urea products and enhance the enterprise′s ability to resist risks. The production process and product quality indicators of vehicle urea are summarized. Furthermore, the reasons for the significant changes in urea concentration in the preparation tank, long preparation time, contamination of product in the finished product tank, and excessive levels of aldehydes in the product during the actual operation of the vehicle urea unit are analyzed. After taking corresponding measures, the stable operation of the vehicle urea unit is achieved, and the product quality met the requirements of national standards.
